  The present invention relates to a fixing member

  intermediate position, to mount a wiper blade on

an associated maneuvering arm.

  It is known that the maneuvering arms in question can

  It may be necessary to provide several types of intermediate fasteners for the different types of operating arms on which the windscreen wiper blades

  to be fixed. In other words, in normal commercial packaging

  incorrectly provided for spare wiper blades, it is necessary to put a number of intermediate fasteners with each broom or each pair of brushes, one broom fastener and for each of the different types of maneuvering arm. Since the user only needs a single broom fastener, the

  other fasteners are then good to throw.

  The object of the invention is to provide an intermediate fixing member, for mounting a wiper blade on several kinds of operating arm, avoiding the disadvantages that have just been exposed; the fastener

  according to the invention which can be used for mounting in-

  differently a wiper blade on maneuvering arms

  to reduce the number of fasteners to be placed in the commercial packages of windscreen wiper blades, in order to ensure a more advantageous price, and to facilitate the work of the user who no longer needs to choose between several

  fasteners for the same broom.

  According to the present invention, there is provided for connecting a wiper blade and an operating arm,

  having a plurality of bearing surfaces at least

  choice of different maneuvering arms. This fixing member being characterized in that

  that these surfaces also provide a fixation for

  the displacement between said arms and said element.

  We will now describe as an example not

  one embodiment of the invention, in

  this in the accompanying drawings, in which: FIG. 1 is a partial sectional view of a wiper blade according to the invention, with its intermediate fixing member; Fig. 2 is a plan view over the wiper blade of FIG. 1; Fig. 3 is a section of the intermediate fastener of Figure 2, following III-III;

  Figs. 4 and 5 are sections of the fixing member

  FIG. 3, along IV-IV and V-V, respectively;

  Fig. 6 represents the intermediate fixing member

  diaire of Figure 1, in the open position; Figs. 7 and 8, similar to Figure 3, are sectional views of the intermediate fixing member of the wiper blade according to the invention, mounted on actuating arms of different dimensions;

  Figs. 9 and 10 are sections of the fixation member

  intermediate of Figure 7, according to IX-IX and X-X respectively; Figs. 11 and 12 are sections of the intermediate fastener of FIG. 8, along XI-XI and

XII-XII respectively.

  In the embodiment of Figures 1 and 2, the wiper blade has a central portion 1, provided with a central opening 2, defined by two walls

  3 between which is normally fixed

  transverse cheeks 4. on it can be mounted, as is explained below, an intermediate member 5 according to the invention, which serves to fix the wiper blade on a maneuvering arm 6. As one as can be seen in FIG. 3, the operating arm 6 has a bent end formed

  rectilinear upper part 7, of an intermediate part

3 2562013

  curve 8, and a rectilinear lower part 9.

  The intermediate fixing member 5, also shown in FIG. 6, is formed of two parts 11 and 11 'which are symmetrical with respect to a median plane and which is convenient to produce, for example, from molded plastics material.

  by injection, connecting them to each other by means of a

  Thin Watch 12, which also plays the role of a hinge

  between the two parts 11 and 11 ', to enable them to

  beating in the closed position around the operating arm 6. Inside the two parts 11 and 11 'of the intermediate fixing member 5, three channels 13, 14 and 15 are made by molding in the two parts, where panels overlap partially, with different dimensions

  in width and height, and different positions.

  Each of these channels is adapted to receive an arm of

  6, 6 'or 6 ", each channel being designed to match the particular dimensions of an arm, in height and in width, it is seen in Figure 3 the mounting mode of the operating arm 6 in the channel 14. The other channels 13 and 15 may receive other actuating arms having different dimensions, in particular the channel 13 may receive a maneuvering arm 6 '(Figure 7) of greater thickness and greater width than the arm 6 (as can be seen

in Figures 9 and 10).

  On the other hand, the channel 13 can receive another operating arm 6 "(Figure 8), as can also be seen in Figures 10 and 11, the arm 6" is wider than

  the arms 6 and 6 ', and has an intermediate thickness.

  As can be seen in Figure 6, the

  lower line of channel 13, corresponding to the branch

  bottom 9 "of the arm 6", ends in the fixing member

  intermediate 5, further from the edge of this member than the end of the lower rectilinear branch of the channel 15,

  corresponding to the branch 9 'of the operating arm 6'.

  As can clearly be seen in Figures 4, 9

4 2562013

  and 11, the operating arms 6, 6 and 6 "each have their curved intermediate portion 8, 8 'and 8" entirely supported by its entire surface inside the fixing member

  intermediate 5 o these curved parts are thus im-

  mobilized and prevented from moving. As for the parts

  rectilinear lines 7, 7 'and 7 "and to the rectilinear

  9, 9 'and 9 "of the arms 6, 6' and 6", they are only partially in abutment against the corresponding internal surfaces of the intermediate fixing member 5,

  as shown in Figures 5, 10 and 12. This contact par-

  However, it is sufficient to ensure that

stable position.

  To set up the intermediate fastener

  according to the present invention, the procedure is

follows.

  Depending on the kind of actuating arm 6, 6 'or 6 "which exists on the vehicle in question, the curved end of this arm is engaged in one of the channels 13, 14 or 15 of the intermediate fixing member 5. , in the open position, as shown in FIG.

  vote on their hinge 12. Then, the wiper of the wiper is mounted in the intermediate fixing member 5, by engaging the pin 4 of the blade in a cavity 16 of the fixing member 5, and pushing the pin 4 to the bottom of the cavity 16. A resilient retaining tongue 17, integral with a wall 18 of the cavity 17 in each of the halves 11 and 11 'of the fastener 5, protrudes inside. of the cavity 17, to elastically fade at

  passage of pin 4, in order to lock pin 4 in position

  service in the bottom of the cavity 16, as shown schematically in Figures 1, 3, 7 and 8 while allowing the wiper of the wiper to rotate about the axis of its pin 4 by

  relative to the intermediate fastener.

  The total width of the two halves 11 and 11 'of

2562013

  the intermediate fixing member 5 is substantially equal to the width of the central opening 2, which is provided in the blade of the windscreen wiper 1 for the housing of the fixing member 5. Thus, the two halves 11 and 111 of the member 5 remain closely attached one against the other, so as to secure these two halves 11 and 11 'with the operating arm 6, 6' or 6 ", without the possibility of relative displacement It can thus be seen that the intermediate fixing member 5 in accordance with the invention makes it possible to advantageously ensure the

The proposed manufacturing method for the intermediate fastener 5, in two halves 11 and 11 'which open symmetrically with respect to a median plane of the fastener 5, also allows a very simple manufacture of this organ , by molding, and

therefore an economic production.
